Saudi-Houthi tensions are rising again after the Iran-backed group released a new video titled "Escalation for Escalation," showcasing tunnel networks, combat drills and preparations for a wider conflict. The footage surfaced just days after the Houthis claimed strikes on Saudi-backed forces in Marib and shortly after Saudi Arabia, Turkey and Pakistan signed a new defense agreement. Is the timing merely symbolic, or a calculated warning aimed at Riyadh and its allies? As regional alliances shift, could this be the opening signal of an even bigger confrontation?
